Setting Up the Printer
Choosing a Place for the Printer
There are several important things to consider when selecting a place to
set up your printer. Keep the following in mind:
Place the printer on a flat, hard, stable surface. A soft surface, such
as a padded counter or carpeted area, will block the ventilation
slots and may cause overheating.
Place the printer close enough to the computer for the printer cable
to reach.
Leave adequate room around the printer to allow for easy printer
operation and maintenance, and for unrestricted flow of air around
the printer.
Use a grounded outlet; do not use an adapter plug.
WARNING: Avoid locations that are subject to direct sunlight,
I
excessive heat, moisture, or dust,
I
Avoid electrical outlets controlled by wall switches or automatic
timers. Accidental interruption of power can wipe out information
in your computer’s memory and in your printer‘s memory.
Avoid using outlets that share a circuit with large motors or
electrical appliances; this could cause fluctuations in line voltage.
Keep the entire computer system away from potential sources of
electromagnetic interference such as loudspeakers or the base units
of cordless telephones.

Choosing a Place for the Printer
The illustration below shows a good printer location.
Note: Before using a printer stand, read these requirements and
suggestions.
l

l
1-6
The stand should be able to support at least twice the weight of
the printer, or approximately 36 pounds (16 kilograms).
Never use a stand that supports the printer at an angle of more
than 15 degrees from horizontal.
With a cut sheet feeder, your printer must be kept level.
If your paper supply is positioned below the printer stand, make
sure there is enough clearance to keep the paper from catching on
the underside of the stand. Also, make sure the distance between
the stand supports is wide enough for the paper you are using.
Position your printer’s cables so that they do not interfere with
paper feeding. If possible, secure the cables to the printer stand.
Setting Up the Printer
Assembling the Printer
After you’ve decided on the best place to set up your printer, the next
step is to install the platen knob.
WARNING: Be sure to remove the locking clip as described in
Installing the Platen Knob
The platen knob is used to feed the paper manually in the event of a
paper jam or other paper feeding problem. The platen knob is packed
in an indentation in the printer’s white foam packing material.
1.
Insert the knob into the hole on the printer’s side and rotate it
slowly until it slips onto the shaft.
Setting Up the Printer
1-7
Assembling the Printer
2.
Push firmly on the platen knob until it fits against the printer case.
CAUTION: Do not use the platen knob to adjust the position
of the paper. This interferes with the automatic paper loading
system and may cause a paper jam.
Installing the Ribbon Cartridge
Your printer’s ribbon cartridge is designed for easy installation and
removal. Before installing the ribbon cartridge, make sure the printer is
turned off.
1-8
Setting Up the Printer
Assembling the Printer
Install the ribbon cartridge as follows.
1.
Slide the print head to the middle of the printer.
CAUTION: Never move the print head while the printer is
turned on because this can damage the printer. Also, if you
have been using the printer, the print head may be hot; let it

Testing the Printer
If the Self Test Does Not Work
If the self test does not print properly, check the control panel and the
print head area. If paper is jammed, turn off the printer. Then remove
the paper using the platen knob and load a new sheet. Make sure that
all packing material and shipping restraints have been removed from
inside the printer. See the Removing the Protective Materials section in
this chapter for information on removing the locking clip. You can also
see Chapter 7 for further information.
Problem
Solution
The printer sounds like
it is printing, but
nothing is printed.
The ribbon may not be installed properly.
Turn off the printer, reinstall the ribbon
cartridge, and then tighten the ribbon by
turning the ribbon-tightening knob. Make
sure the ribbon passes between the print head
and ribbon guide. See page 1-10.
The ribbon may be worn. Replace the ribbon
cartridge. See page 6-5.
The test did not print
when you pressed the
ON LINE button.
Turn off the printer and repeat the self test.
Make sure you hold down the FORM FEED or
LINE FEED button the entire time you are
turning on the printer.
Turn off the printer and disconnect the cable
from the host computer. Try the self test
again.
If the printer still does not print the self test
correctly, contact the store where you
purchased your printer or call the Epson
toll-free number (1-800-922-8911).
1-22
Setting Up the Printer
Connecting the Printer to Your Computer
If the self test printed correctly, you are now ready to connect the
printer to your computer.
If your computer has a parallel interface and you have a suitable
shielded cable, you should be able to connect your printer immediately.
The steps below describe how to connect the parallel interface cable.
If your computer requires another type of interface, you need to install
an optional interface board. See the Interface Boards section in
Chapter 5.
If you are not sure which type of interface cable is required, see your
computer manual.
The Parallel Interface
Connect the parallel interface cable as described below:
1.
Make sure that both your printer and computer are turned off.
Setting Up the Printer

Setting Up the Printer
1-25
Setting Up Your Application Software
Now that you have set up and tested the printer, you should make sure
that it works with your application programs.
Most application programs let you specify the type of printer you are
using so that the program can take full advantage of the printer’s
features. Many of these programs provide an installation or setup menu
that presents a list of printers to choose from.
If your application program has a printer selection menu, use the
instructions below.
Choosing From a Menu
Because the family of Epson printers shares a great many commands,
you can use an application program even if it does not list the
ActionPrinter 4500 on its printer selection menu. If the ActionPrinter
4500 is not listed, choose one of the following printers. They are listed
in order of preference.
LQ-1010
LQ-1050
LQ-2550
LQ-2500
LQ-1000
LQ-1500
If none of these printers is listed, select the first one available on the
following list:
LQ
EX
FX
LX
RX
MX
Epson printer
Standard printer
Draft printer
To use all of the features of the printer, however, it is best to use a
program with the ActionPrinter 4500 or an LQ printer on its menu. If
your program does not list the ActionPrinter 4500 or an LQ printer,
contact the software manufacturer to see if an update is available.

Selecting a Paper Feeding Method
The paper release lever on the printer has three positions for use with
the various methods of paper feeding. Make sure the paper release lever
is set to match the desired paper feeding method.
The lever positions are marked by three icons, as described below.
Single-sheet mode: When you load single sheets from either the
paper guide or from the optional cut sheet feeder, the lever
should be set all the way back to the single-sheet position.
Push tractor mode: When you load continuous paper with the
built-in push tractor, the lever should be set in the middle,
which is the push tractor position.
Pull tractor mode: When you load continuous paper with the
optional pull tractor, the lever should be set all the way forward
to the pull tractor position. Even when you use the built-in push
tractor with the pull tractor, you must set the lever to this
position. Select this position only if you are using the optional
pull tractor.
2-2
Paper Handling
Using Single Sheets
Your printer can accommodate single sheets with a width of 7.2 inches
or 182 mm to 14.3 inches or 364 mm.
If you do most of your printing on single sheets, you may find it more
convenient to install the optional cut sheet feeder. This option
automatically inserts a new sheet and can hold up to 150 pages. For
more details, see Chapter 5.
Loading Paper

You are now ready to begin printing.
Reloading During Printing
When you print a document of more than one page using single-sheet
paper, the printer stops printing when it reaches the bottom of the page.
When this happens, the ON LINE light either goes off automatically or
remains on, depending on your application program software. If the ON
LINE light remains on, the first thing you should do is press the ON LINE
button to take the printer off line.
Once the ON LINE light is off, remove the sheet that has just been
printed (if necessary, press the LOAD/EJECT button to eject the page) and
load a new sheet. Press the ON LINE button to start printing the next
page and follow any additional prompts from your software. Be sure
that the page length or form length setup in your software matches the
number of lines that can be printed on your paper.

Paper Handling
Using Continuous Paper
The push tractor built into your printer is remarkably easy to load and
operate. Its low-profile design takes up little space and can handle
paper up to 16 inches or 406 mm wide.
Positioning Your Continuous Paper Supply
An important consideration for achieving smooth and trouble-free
paper feeding is the position of your paper supply.
Three ways of positioning your printer and continuous paper supply
are shown below.

Printing on Special Paper
In addition to printing on single sheets and continuous paper, your
printer can also print on a wide variety of paper types, including
multi-part forms, labels, and envelopes.
Before printing on special types of paper, you need to change the paper
thickness setting.
I!!7
WARNING: When printing on multi-part forms, labels, or
envelopes, make sure that your application program settings
keep the printing entirely within the printable area.
For multi-part forms and labels you should not print any
closer than one-half inch from either side of the paper.
For information on the printable area for envelopes, see page
2-31.
The Paper Thickness Lever
To accommodate various thicknesses of paper, your printer is equipped
with a paper thickness lever that can be set to eight positions. These
positions are identified by a scale on the printer next to the lever. (See
the chart on page 2-26.)
2-24
Paper Handling
Printing on Special Paper
To change the paper thickness setting, follow these steps.
1.
Make sure that the printer is turned off. Then remove the printer
cover.
WARNING: If the printer has just been in use, the print head
may be hot. Allow it to cool before touching it,
2.
Select the paper thickness you want according to the table on the
following page. For normal use, the lever should always be set to
position 2 on the scale.
To help you check the position of the paper thickness lever, the
orange MULTI-PART light on the control panel comes on if the lever
is set to position 4 or higher.

WARNING: Always return the lever to position 2 when you
go back to printing on ordinary paper. Continuous printing
with the lever set at a position higher than 2 can shorten the
life of the print head. Also note that printing past the edge of
envelopes, multi-part forms, labels, or thicker-than-normal
paper can damage the print head.
Multi-part Forms
With the built-in tractor unit, your printer can print on continuous
multi-part forms. You can use multi-part forms that have up to three
parts including the original. Make sure you set the paper thickness lever
to the proper position; see the table on page 2-26.
Paper Handling
2-27
Printing on Special Paper
Except for the paper thickness lever setting, you load multi-part paper
the same way as continuous paper. For details, see the section on
loading continuous paper in this chapter. Also see the sections on
setting the loading position and page length in Chapter 3.
CAUTION: Multi-part forms should not be used with the
single-sheet feeding system or the optional cut sheet feeder.
Labels
If you need to print labels, always use labels mounted on a continuous
backing sheet with sprocket holes for use with a tractor. Do not try to
print labels as single sheets because labels on a shiny backing sheet
almost always slip a little.
2-28
Paper Handling
Printing on Special Paper
You load labels the same way that you load continuous paper except
that the paper thickness lever must be adjusted for printing labels. See
the section on loading continuous paper earlier in this chapter. For the
correct paper thickness setting, see the table on page 2-26.
WARNING: Never feed labels backward through the printer.
Labels can easily peel off the backing and jam the printer.
Therefore, never use the LOAD/EJECT button to eject labels.
Also, never use the short tear-off function with labels. (Be
sure to set DIP switch 2-2 to off .) If a label does become
stuck in the printer, call the Epson toll-free number
(1-800-922-8911) for assistance.
Since labels are especially sensitive to temperature and
humidity, always use them under normal operating
conditions. Don’t leave labels loaded in the printer between
jobs; they curl around the platen and may jam when you
resume printing.
Paper Handling

Envelopes
You can feed envelopes individually using the single-sheet loading
feature. Before loading envelopes, adjust the position of the paper
thickness lever according to the table on page 2-26. For details on paper
handling, see Using Single Sheets on page 2-3.
When manually feeding an envelope, you may have to push it down
slightly while pressing the LOAD/EJECT button to get it to feed properly
CAUTION: The printable area for envelopes is shown on the
next page. The print head must not go past the left or right
edge of the envelope or other thick paper. Make sure that
your application program page setup keeps the printing
entirely within this printable area.

Setting the DIP Switches
Your printer has two sets of DIP (Dual Inline Package) switches located
under a small cover above the control panel. By changing the settings
of these switches, you can control various printer features, such as the
character set and page length. The new settings become effective when
the printer is turned on, reset, or initialized.
DIP switch settings are shown in the DIP switch tables starting on page
3-7. Descriptions of all the DIP switch functions begin on page 3-9.
Changing a DIP Switch Setting
To change a DIP switch setting, first turn off the printer. Then open the
DIP switch cover and use a pointed object, such as a pen, to change the
DIP switch settings. A DIP switch is on when it is up, and off when it is
down.
The new DIP switch settings take effect when the printer is turned on.

The input buffer stores data from your computer. If you want to free
your computer for other tasks while the printer prints, change the
setting of switch 2-5 to 8 KB (on). Before using user-defined characters,
however, be sure to set the input buffer to 1 KB (off).
Tear-off mode
When DIP switch 2-2 is on, the short tear-off mode is on. This feature
automatically advances continuous paper to the tear-off position, and
then reverse-feeds the paper to the loading position. See the section on
using short tear-off later in this chapter.

Skip Over Perforation
By changing the setting of DIP switch 2-3, you can set skip over
perforation to on or off. If this feature is on when using continuous
paper, a one-inch margin is provided between the last printable line on
one page and the first printable line on the next page. This feature is
very convenient if your application program does not provide for top
and bottom margins.
If you adjust your loading position correctly, you can get half of the
margin at the bottom of one page and half at the top of the next page,
as shown in the following illustration.

Using the Printer
3-11
Adjusting the Loading Position
The Loading Position
The loading position is the position of the paper when it has been
loaded automatically by the printer.
This position is important because it determines where the printing
begins on the page. If the printing is too high or too low on the page,
change the loading position using the micro-adjustment feature
described in the next section.
CAUTION: Never use the platen knob to feed paper except in
case of a paper jam or other paper feeding problem. (If you
need to use the platen knob, make sure the power is off.) If
you need to adjust the loading position, always use the
micro-adjustment feature.
Until the loading position is reset, the printer remembers this position
even if it is turned off, and uses it as a reference point for feeding paper.
The micro-adjustment feature moves the paper in 1/180-inch
increments to make fine adjustments to the loading position. Once you
have used micro-adjustment to change the loading position of
continuous paper, the printer remembers that position even after it is
turned off.
When you use micro-adjustment to change the loading position of
single-sheet paper, however, the printer does not remember this position
after the power is turned off. When the power is turned back on, the
loading position returns to its factory setting.

Note: When the paper reaches the factory-set loading position,
the printer beeps and micro-adjustment feeding pauses for a
moment before continuing. You can use this factory setting as a
reference point when adjusting the printer’s loading position.
When the paper reaches either the minimum or maximum top
margin, the printer beeps and the paper stops moving.
3-14
Using the Printer
Using Short Tear-Off
When you are finished printing, the short tear-off feature automatically
feeds the perforation of the continuous paper to the tear-off edge of the
printer cover so that you can tear off the last sheet. When you resume
printing, the paper feeds backward to the loading position. This feature
lets you save the paper normally lost between documents.
To use this feature, set DIP switch 2-2 to on, and make sure that the
length of the continuous paper matches the length set by DIP switch
2-1. Then load continuous paper in the normal way.
0t
.
CAUTION: To change the setting of a DIP switch, first turn
off the printer, change the DIP switch setting, and then turn
the printer back on.
You can leave the short tear-off feature turned on (DIP switch 2-2 on)
even when you are using single sheets. When you move the paper
release lever to the single-sheet position, the short tear-off feature is
disabled.
WARNING: Never use short tear-off with labels. Otherwise,
labels may come off their backing and jam the printer.
When you have finished printing, if the perforation is at the top of form
position, the printer automatically feeds the perforation of the
continuous paper to the tear-off edge of the printer cover. You can then
tear off the page using the tear-off edge as shown on the next page.
Using the Printer
3-15
Using Short Tear-Of
If the page perforation is not properly aligned with the tear-off edge,
you can adjust the tear-off position using micro-adjustment, as
described below.
Note: Short tear-off is not performed unless printing of a page is
completed and the paper has advanced to the top of the next page.
When you resume printing after tearing off the sheet, the paper
automatically feeds backward to the loading position before printing
begins.
Adjusting the Tear-off Position
If the paper‘s perforation does not meet the tear-off edge, you can
adjust the tear-off position using the micro-adjustment feature.

Selecting Typestyles
You can produce a wide range of typestyles by selecting different
character fonts, widths, and other enhancements from the SelecType
control panel or by using software commands. This section describes
only the features controlled by SelecType. To use software commands,
see the Command Summary in Chapter 9.
You can use the SelecType section of the control panel to choose fonts
and condensed printing. Orange lights indicate which features you have
chosen. For example, if both indicator lights are lit, the slot is selected
for your optional font cartridge (if one is installed).

Selecting Typestyles
Note: The settings you select using the SelecType panel remain valid
until the printer is turned off or until it receives other instructions
from software. Some application programs, however, are designed to
control all typestyle functions, These programs cancel all previous
typestyle settings by sending certain software commands before
printing. Because these commands override SelecType settings, you
should use the program’s print options instead of SelecType to select
your typestyles. If SelecType does not work with a particular
application, check your software manual for instructions on selecting
typestyles.
Character Fonts
Your printer has three built-in fonts:
DRAFT
ROMAN
'"#$%&'()*t,-./0123456789:;<=>?BABCDEFGHIJK
LMNOPQRSTUVWXYZ'F§^-'abcdefghijklmnopqrstuv
SANS SERIF
3-20
Using the Printer
Selecting Typestyles
The DRAFT mode uses fewer dots per character for high-speed printing,
which makes it ideal for rough drafts and editing work.
ROMAN and SANS SERIF are Letter Quality (LQ) fonts. Letter Quality
takes a little longer to print, but produces nicely formed characters
suitable for most documentation requirements.
Other fonts are available on optional font cartridges. See Multi-Font
Module in Chapter 5.
Condensed Mode
You can use the condensed mode to change the size of printed
characters. In the condensed mode, characters are approximately 60
percent of the width of normal characters. Hence, condensed printing is
very useful for spreadsheets and other applications where you need to
print the maximum amount of information on a page. You can combine
the condensed mode with 10 and 12 cpi printing, but not 15 cpi.
To select the condensed mode, simply press the CONDENSED button so
that the orange indicator light comes on. To turn off the condensed
mode, press the button again.
The following printout compares normal 10 and 12 cpi with condensed
10 and 12 cpi. The condensed 10 cpi is 17 cpi, and the condensed 12 cpi
is 20 cpi.
This is 10 CPI printing.
This is condensed 10 CPI printing,
This is 12 CPI printing.

International character sets provide you with the characters and
symbols used in other languages. You can select one of eight
international character sets by changing the DIP switch settings.
Whenever the printer is turned on, reset, or initialized, the character set
selected by the DIP switches becomes the default character set.
To select an international character set, set DIP switches 1-1, 1-2, and

You can obtain a wide variety of printing effects with your printer,
from changing the number of characters per inch to using special effects
on selected words and phrases. This section gives you a sampling of the
features you may select with your software.
For software control of these features, see the instructions for your
application programs or look up their specific commands in the
Command Summary in Chapter 9.
Character Spacing
To add greater variety to your documents, your printer has three cpi
spacings, as well as proportional spacing. Each one can be selected with
a software command.
For each of the three built-in fonts, you can choose a character spacing
of 10, 12, or 15 characters per inch, or proportional spacing. The
printout below compares the three cpi spacings:
This is 10 cpi printing.
This is 12 cpi printing.
This is 15 cpi printing.
As shown above, 15 cpi characters are only about two-thirds the height
of 10 and 12 cpi characters. This makes 15 cpi particularly useful when
you want to separate certain material from the main text.
In fixed cpi spacing each character is given the same amount of space.
The width of proportional characters, however, varies from character
to character. For example, a narrow letter like i takes less space than a
wide letter like W. The width of each proportional character is given in
the Appendix.

Character Size
In addition to the basic cpi spacings and proportional spacing, your
printer offers three other modes that can change the size of your
printing. These modes are double-wide, double-high, and condensed.
The double-wide mode doubles the width of any size character, while
the double-high mode doubles the height of any size character. These
modes are useful for emphasizing document titles and headings in
reports, but are usually not suitable for large amounts of text. These
modes can also be combined to obtain even more impressive printing
results.

Enhancing Your Printing
Both 10 and 12 cpi printing can be reduced to about 60 percent of their
normal width using the condensed mode. This mode is particularly
useful for printing wide spreadsheets because condensed 12 cpi printing
allows you to print up to 272 characters on a 13.6-inch line.
The condensed mode can be selected with a software command, or by
using SelecType (see Chapter 3). Even if you turn the condensed mode
on with SelecType, you can still turn it off with a software command.
Condensed 10 cpi gives you many characters on a line,
Condensed 12 cpi gives you even lore characters on a line,
Widening or narrowing the characters also widens or narrows the
spaces between words. Because word processors usually create a left
margin by printing spaces, you may need to change the left margin and
the number of characters on a line to keep the margins correct if you
change character widths.
Special Effects and Emphasis
The printer offers two ways of emphasizing text and also allows you to
use underlining, superscripts, subscripts, and italics. These features can
be controlled directly by software commands. Many application
programs can also produce some of these effects. See your application
program manual for details.
Emphasized and double-strike printing
Emphasized and double-strike printing can give words and phrases
added prominence. In emphasized mode, each character is printed twice
as the print head moves across the paper, with the dots in the second
pass printed slightly to the right of the first pass. This process produces
darker, more fully formed characters.

Enhancing Your Printing
In double-strike mode, the print head prints each line twice, making the
text bolder. For even greater boldness, emphasized and double- strike
can be combined. The following samples show the different effects you
can achieve using these modes alone and in combination.
This is ROMAN printing.

Underlining, strike-through, and overlining
The underline, strike-through, and overline modes are useful for
highlighting selected text. This feature can be used to score spaces,
subscripts, and superscripts without a break. You can choose from a
variety of line styles, including single, double, broken, or continuous.

plus a combination of outline with shadow.
Selecting Typestyles With Master Select
Your printer has a special ESCape code called Master Select that allows
you to choose many combinations of these nine modes: 10 cpi, 12 cpi,
proportional spacing, condensed, emphasized, double-strike,
double-wide, italics, and underline. For more information on sending
ESCape codes to your printer, see Chapter 9.

Graphics
The dot graphics mode allows your printer to produce pictures, graphs,
charts, or almost any other pictorial image you can create.
Because many commercial software programs use graphics, you may be
able to print pictures and graphs like the ones on this page and the next
by simply giving your software a few instructions.
The quickest and easiest way to print graphics on your printer is to use
a commercial graphics program. With such programs you usually
create an image on your monitor then give a command to send the
image to the printer.
If you use commercial software that produces graphics, all you need to
know about dot graphics is how to use the software. The application
program will take care of the printer. (Some programs call this bit
image printing.) On the other hand, if you wish to do your own
programming or merely wish to understand how this printer prints
graphics, read on.

The Print Head
To understand dot graphics you need to know a little about how your
printer’s print head works.
The print head has 24 pins. As the print head moves across the page,
electrical impulses cause the pins to fire. Each time a pin fires, it strikes
the inked ribbon and presses it against the paper producing a small dot.
As the print head moves along, the pins fire time after time in different
patterns forming letters, numbers, and symbols.
Because the dots overlap each other both horizontally and vertically in
Letter Quality mode, it is difficult to see the individual dots. Instead,
the letters and symbols seem to be made up of unbroken lines.
In order for the dots to overlap vertically, the pins in the print head are
in more than one column, but the intelligence of the printer handles the
timing of pin firings so that the effect is that of 24 pins arranged in a
single vertical column.
Dot patterns
The print head is able to print graphics as well as text because graphic
images are formed by the printer in about the same way that pictures in
newspapers and magazines are printed. If you look closely at a
4-10
Software and Graphics
Graphics
newspaper photograph, you will find that it is made up of thousands of
small dots. Your printer also forms its images with patterns of dots, as
many as 360 dots per inch horizontally and 360 dots per inch vertically.
The images printed by this printer can, therefore, be as finely detailed
as the ones at the beginning of this section.
Twenty-four-pin graphics
The graphics mode that takes full advantage of this printer’s print head
is 24-pin graphics. This mode has five densities, but for simplicity this
explanation deals with only one of them, triple-density.
Triple-density prints up to 180 dots per inch horizontally. As the print
head moves across the paper, every 1/180th of an inch it must receive
instructions about which of its 24 pins to fire. At each position it can
fire any number of pins, from none to 24. This means that the printer
must receive 24 bits of information for each column it prints. Since the
printer uses S-bit bytes of information in communicating with the
computer, it needs three bytes of information for each position.
Pin labels
To tell the printer which pins to fire in each column, you first divide
each of the vertical columns into three sections of eight pins each and
consider each section separately. Since there are 256 possible
combinations of the eight pins in each section, you need a numbering
system that allows you to use a single number to specify which of the
256 possible patterns you want. This numbering system is shown
below :
Software and Graphics
4-11
Graphics
To fire any one pin, you send its number to the printer. To fire more
than one pin at the same time, add up the numbers of the pins and send
the total. Using these labels for the pins, you fire the top pin by sending
128. To fire the bottom pin, you send 1. If you want to fire only the top
and bottom pins, you simply add 128 and 1, and send 129.
By adding the appropriate label numbers together, you can fire any
combination of pins. Below are three examples of how to calculate the
number that will fire a particular pattern of pins.
128
1
32
8
2
170
With this numbering system, any combination of the eight pins adds up
to a decimal number between 0 and 255, and no numbers are
duplicated.
Since there are 24 pins in each column, you must make a calculation for
each of the three sections in each column. As you can see, this method
of planning and printing dot graphics requires considerable calculation.
Because triple-density uses 180 columns per inch, printing a single line
of triple-density graphics only one inch long requires 540 numbers.
Fortunately, commercial graphics software is available to do these
calculations for you.
Before you can put these numbers into a graphics program, however,
you need to know the format of the graphics command.

Graphics
The Graphics Command
The graphics mode command is quite different from the other
commands used by the printer. For most of the other printer modes,
such as emphasized and double-wide, one ESC code turns the mode on
and another turns it off. For graphics, the command is more
complicated because the code that turns on a graphics mode also
specifies how many columns it will use. After the printer receives this
code, it interprets the numbers that follow as pin patterns and prints
them on the paper.
Your printer has one command that allows you to use any of the 11
graphics options. The format of the command is:
ESC * m n1 n2 data
In this command, m selects the graphics option and n1 and n2 specify
the number of columns to reserve for graphics. The available graphics
options are listed below:
* Adjacent dots cannot be printed in this mode.

Column Reservation Numbers
The graphics command requires more
many columns to reserve because one

decimal. Therefore the graphics mode
and n2, for reserving columns.
than one number to specify how
line can use thousands of
numbers larger than 255 in
command uses two numbers, n1
To find n1 and n2, divide the total number of columns by 256. The
result is n2; the remainder is n1. Since the command is set up for two
numbers, you must supply two even if you need only one. When you
need fewer than 256 columns, just make n1 the number of columns you
are reserving and make n2 a zero.
For example, if you wish to send 1632 columns of graphics data, n1
should be 96 and n2 should be 6 because 1632 = 96 + (6 x 256).
The printer interprets the number of bytes specified by n1 and n2 as
graphics data, no matter what codes they are. This means that you
must be sure to supply enough bytes of graphics data or the printer will
stop and wait for more data and will seem to be locked. If, on the other
hand, you supply too much graphics data, the excess will be interpreted
and printed as regular text.
A Simple Graphics Program
This first program is just a simple example to show you how the
graphics command, column reservation numbers, and data can be used
in a BASIC program.

Line 20 selects single-density 24-pin graphics mode (mode 32) and also
reserves 40 columns for graphics. Since 24-pin graphics requires three
bytes of data for each column, line 30 begins a loop to supply 120 bytes
of data. Line 40 contains the number 170, which produces the first pin
pattern shown in the section on pin labels, and line 50 ends the loop.
Designing Your Own Graphics
With what you know now, you can use the simplest application of
graphics-calculating by hand the data to print the graphic image.
While this method is the most tedious, it helps you understand dot
graphics. It is also useful for small graphic elements that are used many
times.

The illustration below shows how you can use a grid on paper to plan
where you want dots to be printed. This grid is for a single line of
graphics 42 columns long. Since each line of 24-pin graphics is
approximately 1/8th of an inch high and since triple-density graphics
prints 180 dots per inch horizontally, a design planned on this grid will
be about 1/8th of an inch high and less than 1/8th of an inch wide.
!
/
I
The actual pattern that the printer prints on the paper is, of course,
made up of dots that overlap each other both vertically and
horizontally. The reason the planning grid uses an x for each dot is that
using an accurate representation of the dots makes calculating the data
numbers difficult because they cover each other. Therefore, remember
that each x represents the center of a dot, and the dots actually overlap.
Write the assigned values of the pins next to your design, then total the
values for each column of dots. These totals are the values that you
send to the printer as graphics data to print the design.

User-defined Characters
With this printer, it is possible to define and print characters of your
own design. You can design an entirely new alphabet or typeface,
create special characters for use as mathematical or scientific symbols,
or create graphic patterns with user-defined characters to serve as
building blocks for larger designs.
Below, you can see samples of typefaces created with the user-defined
character function.
Note: To use user-defined characters, you must turn DIP switch 2-5

You can make the task of defining characters easier by using a
commercial software program that assists you in creating characters or
simply supplies you with sets of characters already created. Also, some
popular software programs make use of the printer’s user-defined
character function to enhance printouts. (These characters are called
download characters in some programs.)
The standard ASCII characters are stored in the printer’s Read Only
Memory (ROM) or optional Multi-Font Module, and the user-defined
characters are stored in the printer’s Random Access Memory (RAM).
Designing Your Characters
User-defined characters are like dot graphics because you send the
printer precise instructions on where you want each dot printed. In
fact, planning a user-defined character is like planning a small dot
graphics pattern.
4-20
Software and Graphics
User-defined Characters
Design grids
To design a character you use a grid that is 24 dots high-one dot for
each pin on the printer’s print head. The width of the character matrix
depends on the character set in use. For draft characters, the grid is nine
dots wide, for Letter Quality it is 29 dots wide, and for proportional
characters it is 37 dots wide. The dots for both Letter Quality and
proportional characters are spaced more closely together than those for
draft characters.
The illustrations below show the two design grids. The line at the side,
labeled cap, indicates the top of a standard capital letter. The line
labeled base indicates the baseline for all letters except those with
descenders (the bottom parts of such letters as j and y). The bottom
row is usually left blank because it is needed for underlining.
The grid on the right side can be used for either Letter Quality or
proportional characters. For Letter Quality you do not use all the
columns.

User-defined Characters
There is one restriction in designing characters. Dots in the same row
may not print in adjacent columns. This means that there must be an
empty dot position both to the left and right of each dot that prints.
This is true in draft, Letter Quality, and proportional mode.
Defining Your Characters
The first step in defining characters is to place the dots on a grid just as
you want them to print. The examples shown here, like the ones in the
graphics section, use an x to represent each dot.
In the illustration below, you see a draft grid with a simple userdefined character planned on it.
Now you translate the dot pattern you’ve created on paper to a
numeric format so you can send the data to your printer. Every dot has
an assigned value. Each vertical column (which has a maximum of 24
dots) is first divided into three groups of eight dots. Each group of eight
dots is represented by one byte, which consists of eight bits. Hence, one
bit represents one dot.
4-22
Software and Graphics
User-defined Characters
Data numbers
The bits within each byte have values of 1, 2, 4, 8, 16, 32, 64, and 128.
In the vertical column of dots, the bits are arranged so that the most
significant bit (with a value of 128) is at the top of the column and the
least significant bit (with a value of 1) is at the bottom.
The next illustration shows how to use this method to calculate the data
numbers for the character in this example. On the left side of the figure,
the data numbers are calculated for the middle column. The value of
each byte is calculated by adding the values of the rows in which dots
appear. The right side of the figure shows the whole character with the
three data numbers for each column indicated at the bottom.
This manual uses decimal numbers because the program examples are
written in BASIC and everyone is familiar with decimals. The data you
send to your printer, however, must be in the form (binary, decimal, or
hexadecimal) that you can use with your programming language.
Software and Graphics
4-23
User-defined Characters
You have seen how to design a character by placing dots on a grid and
translating the dots to decimal equivalents. The last step in defining a
character is sending this information to your printer.
Sending Information to Your Printer
The printer loads characters in the print style (Letter Quality, draft, or
proportional) that the printer is currently using. It also records whether
italic, superscript, or subscript is turned on. This means that if you
want to print a character in italics, for example, you must have the
italic mode turned on when you define the character.
The command your printer uses to define characters is one of the most
complex in its repertoire. The format of the command is this:
ESC & 0 n1 n2 d0 d1 d2 data
The ESC & is simple enough. The 0 (which is ASCII code 0, not the
character zero in quotation marks) allows for future enhancements. At
this time, it is always ASCII 0.
You can define many characters with a single command. The values n1
and n2 are the ASCII codes of the first and last characters you are
defining. If you are defining only one character, n1 and n2 are the
same. You can use any codes between decimal 32 and 127 for n1 and
n2, but it is best not to define decimal 32, which is the code for a space.
Also, you can use letters in quotation marks instead of ASCII codes for
n1 and n2.
Note: Because user-defined characters require additional memory,
you must set DIP switch 2-5 to 1 KB (off) before downloading these
characters.
4-24
Software and Graphics
User-defined Characters
An example will show how to specify n1 and n2. For instance, if you
wanted to redefine the characters A through Z, n1 would be A (or
ASCII code 65) and n2 would be Z (or ASCII code 90). So the
command ESC & 0 AZ (followed by the appropriate data) would
replace the entire alphabet of capital letters.
Following the specification of the range of characters to be defined in
this command are three data bytes, d0, d1, and d2, that specify the
width of the character and the space around it. The left space (in dot
columns) is specified by d0, and the right space is specified by d2. The
second byte, d1, specifies the number of columns of dots that are
printed to make up the character. By varying the width of the character
and the spaces around it, you can create proportional-width characters
that print at draft speed. The table below shows the maximum values
for these bytes.

The last part of the command to define your characters is the actual
data that defines the dot patterns for each character. Since it takes three
bytes to specify all the dots in one vertical column, your printer expects
d1 x 3 bytes of data to follow d2.

The information about the actual character design (which is contained
in the DATA statements at the end of the program) is sent to the printer
in the loop between lines 50 and 70.
Note: When defining Letter Quality or proportional characters, put
a WIDTH statement in your program to prevent carriage return and
line feed codes from interfering with your definitions.

Printing User-defined Characters
If you entered the previous program example, you defined an arrow
and placed it in the RAM location for ASCII code 64 (replacing the @
sign). You can now print out a three-line sample of your work. The first
and third lines (printed by lines 80 and 120) print the normal @ sign.
The second line (printed by line 100) prints out the arrow that you
defined.
Run the program to see the printout below:
As you can see, both sets of characters (the @ from the original
characters in ROM that the printer normally uses and the alternative
character you defined) remain in the printer available for your use. The
command to switch between the two sets is used in line 90 and 110. It
is:
ESC % n
If n is equal to 0, the normal ROM character set is selected (this is the
default). If n is equal to 1, the user-defined character set is selected. If
you select the user-defined character set before you have defined any
characters, the command is ignored and the ROM characters remain in
use.
You may switch between character sets at any time-even in the middle
of a line. To try this, place semicolons at the end of lines 80 and 100 in
the program example.

Copying ROM Characters to RAM
After running the program, if you select the user-defined character set
and try to print other characters, the only one that will print is your
arrow. Since no other characters are in the printer’s user-defined RAM,
there is nothing else to print. Other characters sent to the printer do not
even print as spaces; it’s as if they were not sent at all.
In many cases, you will want to redefine only a few of the characters to
suit your needs-the rest of the alphabet will work fine as it is. As you
have seen, it is possible to switch back and forth, at will, between the
normal character set and your user-defined character set. It is, however,
rather inconvenient.
Therefore, your printer has a command that allows you to copy all of
the standard characters from ROM to the user-defined character set.
The command format is as follows, where the value of n represents the
font family:
ESC:0n0
Note: This command cancels any user-defined characters you have
already created. You must send this command to the printer before
you define characters.
If you use this command at the beginning of a program, then define
your special characters and select the user-defined set, you can print
with the user-defined set as your normal character set. You never need
to switch back and forth between sets.

User-defined Characters
Letter Quality Characters
If you select Letter Quality printing with the ESC xl command, you
can design user-defined characters using up to 29 columns of the Letter
Quality/Proportional grid. The dot columns are spaced closer together
horizontally than draft dot columns (the horizontal dot spacing is
1/360th of an inch as opposed to 1/120th of an inch for draft
characters).
Proportional mode characters
Selecting the proportional character mode yields user-defined characters
of the highest resolution. Characters can be designed using all 37
columns of the Letter Quality/Proportional grid.
Remember that in Letter Quality and proportional modes, as in draft
mode, you cannot place dots in adjacent columns. There must be an
empty dot position both to the left and right of each dot that prints.
Superscripts and Subscripts
You can also create superscript and subscript user-defined characters.
Just as Letter Quality characters are defined when the Letter Quality
mode is selected, superscript and subscript characters are created when
either superscript or subscript is selected.
These characters can be used as either superscripts or subscripts. The
characters are exactly the same; only their placement is different. The
difference between these characters and regular characters is that
superscript and subscript characters are smaller. They are a maximum
of 16 dots high. Their maximum width in dot columns is shown in the
table below:

Proportional

Software and Graphics

User-defined Characters
Since superscript and subscript characters are smaller, when you define
them you only need two bytes of data for each vertical row of dots.
Design grids for these characters are shown in the figure below:
Draft pica
Letter Quality
and Proportional
Mixing Print Styles
Each of the three user-defined character modes (draft, Letter Quality,
and proportional) can be used in combination with most of your
printer’s various print styles. For instance, emphasized mode works
with user-defined characters. The characters you design are enhanced to
give this printing effect.
Mixing the three types of user-defined character sets is not possible. For
example, if you select draft and define some characters, then select
proportional and define some more, the first draft character definitions
are deleted. Only one type of character definition may be stored in
RAM at any time.
4-30
Software and Graphics
User-defined Characters
If you define characters in one mode, then switch to another mode and
select the user-defined character set, the command is ignored and
nothing is printed. The user-defined character definitions, however,
remain unaffected. If you switch back to the mode in which they were
defined, you can then select and print them.
Keep in mind that user-defined characters are stored in RAM, which is
not permanent memory. When the printer power is turned off or the
printer is initialized with the INIT signal, the user-defined characters are
lost. (Some computers do this each time BASIC is loaded.)

The Interface Boards
A number of optional interfaces are available in case your computer is
either not provided with a parallel interface or you wish to increase the
memory capacity of your printer’s buffer.
Choosing an Interface
Optional interfaces can be divided into three main categories which are
described briefly below.
IEEE-488 interfaces offer standardized connections, trouble-free
operation, and the ability to connect computers, printers, and other
devices on the same line so that they may share data freely.
The buffered parallel interfaces also offer trouble-free operation and
standardized connections. They provide the printer with more
memory to free the computer for other tasks when printing large
amounts of text or graphics. You can increase the printer’s data
buffering capacity by an additional 32 KB (about 10 pages).
Serial interfaces are required if your computer is not equipped with
a parallel interface or if you need an interface that conforms to the
Current Loop standard instead of RS-232C. These interfaces also
provide some combination of the following features: X-ON/X-OFF
data communication protocol, loopback self test modes, and data
buffers that increase the printer’s data buffering capacity.

All Epson interfaces have the Epson name printed on them. If the board
has an identification code printed on it, it is a four-digit number
beginning with 8 and should correspond to one of the numbers listed in
the table above.
Also, Coax and Twinax interfaces are available from third party
vendors. These interfaces allow connectivity to mainframes and
minicomputers and emulation of IBM printers. The Coax (EP-Connect)
is available from Avatar Corporation (508) 435-6872, and the Twinax
(I-O8300) is available from I-O Corporation (801) 973-6767.

If you are using an optional interface, it may be necessary for you to
alter the communication protocol of the printer or the computer so that
they can communicate properly. In most cases, you should use the
information in your optional interface manual or your computer’s

If you are using the #8143 optional interface board, make sure that you
read through the section below on baud rate selection. You may also
want to see the following sections on handshaking timing and error
handling for interface information specific to your printer.

The Interface Boards
Baud rate selection
You can select baud rates from 75 to 19,200 BPS (Bits Per Second).
When setting the baud rate, make sure you use the bit rate selection
table for printers with buffers (in the #8143 interface manual).
For more information on the printer’s input buffer settings, see the
section on DIP switch functions in Chapter 3 of this manual.
Handshaking timing
When the vacant area for data in the input buffer drops to 256 bytes,
the printer outputs an X-OFF code or sets the DTR flag to "1" (MARK)
indicating that it cannot receive data.
Error handling
When a parity error is detected, your printer prints an asterisk (*). All
other errors, including framing and overrun, are ignored.

is on line).
After a print
command is sent from
the computer, the
platen does not move
and the paper does not
feed.
The printer may be off line. Press the ON
LINE button to put the printer on line.

Troubleshooting
The cut sheet feeder mode may be off. Set
DIP switch 1-8 to on. If your program
allows you to use control codes, use ESC
EM 4 to set the cut sheet feeder mode. The
printer must be ready with no paper out
condition to receive this command. Send
the command with continuous paper
loaded and with the paper select lever in
the continuous paper position.

Problem
Solution
Using the cut sheet
feeder, the paper does
not feed properly
(continued).
The paper feed is
crooked.
The paper may be old or creased. Discard
it and load new, clean sheets of paper.
The left and right paper guides may be too
far apart. Adjust the paper guides to the
width of the paper.
There may be too much outgoing paper.
Never let more than 80 sheets of outgoing
paper accumulate while printing.
The weight of your paper may be too
heavy or too light for the cut sheet feeder.
Refer to the specifications in Chapter 8 and
make sure that your paper is the proper
size and quality.
You tried to manually
insert a single sheet,
but instead paper was
fed from the cut sheet
feeder’s bin.
The single sheet may have been inserted in
the wrong place. Check it and try again.
See Chapter 5.
Paper may feed from the bin if you try to
insert several single sheets. To insert several
single sheets, pull the paper set lever
forward.

Options
Problem
Solution
Using the pull tractor
with the push tractor,
continuous paper does
not feed properly
(continued).
Paper feed is crooked
or the paper jams.
Something may be obstructing the paper
feed, like an object on top of the paper
stack or a cable caught on the paper. Make
sure that nothing prevents the smooth flow
of paper and position the paper so that it
feeds straight in line with the sprockets.
The supply of paper may be too far from
the printer. Position the paper supply so
that it is less than three feet or one meter
away.
The paper may be caught on the edge
guides. When using continuous paper,
make sure that the paper guide is folded
backwards over the paper and that the
edge guides are moved to each edge of the
paper guide. See Chapter 2.
The pull tractor and push tractor sprockets
are not aligned correctly. When using both
tractors, be sure that the sprockets on both

Command Summary 9-1
Using the Command Summary
This chapter lists and describes all the commands available on your
printer.
The first part of this chapter lists all commands in numerical order and
gives the number of the page where each is fully described. If you know
which command you are looking for, consult the numerical list.
Note: The Quick Reference card at the end of the book also contains
a list of the commands divided by topic, with page number
references that direct you to full explanations of the commands.
The second part of this chapter lists and describes each command
separately; the commands are divided into the following subjects:
Printer operation
MSB control
Data control
Vertical motion
Horizontal motion
Overall printing style
Print size and character width
Print enhancement
Word processing
Character sets
User-defined characters
Graphics
Each command description has a format section and a comment
section. The format section gives the ASCII, decimal, and hexadecimal
values for the command. These three formats are equivalent, and it
should be easy to pick the one most suited to your purpose. The
comment section describes the effect of the command and gives any
additional information necessary for using it.
Note: Some application programs use control key sequences. See the
Control Key chart on page 9-4.

Command Summary
Using the Command Summary
The simplest type of command consists of a single character to be sent
to the printer. For instance, to print in condensed mode, the code
format is:
ASCII code: SI
15
Decimal :
Hexadecimal: 0F
This code can be sent from a program by sending the code 15 directly.
More complex commands consist of two or more character codes. For
example, to print in double-wide mode, the code format is the
following:
ASCII code:
Decimal:
Hexadecimal:
ESC
27
1B
W
87
57
n
n
n
In this case n can be either 1 (on) or 0 (off), to begin or end double-wide
printing. You can use either of the following commands to turn on
double-wide print from BASIC:
LPRTNT CHR$(27);CHR$(87);CHR$(1)
LPRINT CHR$(27);"W";CHR$(1)
For the following commands that use only 0 or 1 for the variable, either
the decimal or hexadecimal values 1 and 0 or the ASCII characters 1
and 0 can be used:
ESC U, ESC x, ESC p, ESC W, ESC S, ESC-, and ESC %
For example, in BASIC you can turn on proportional spacing with
either of these statements:
LPRINT CHR$(27);"p";CHR$(1)
LPRINT CHR$(27);"p";"1"
Command Summary 9-3
Using the Command Summary
Control Key Chart
Some application programs use control key codes for decimal values
0-27. The table below gives you the proper values. The Control Key
column indicates that you press the control key at the same time you
press the key for the letter or symbol in that column. For example, you
press the control key and A at the same time to send the value 1.
Some application programs that use this system cannot use Control-@,
and many programs use the control keys for other purposes.

calculate the displacement required in dots. If the displacement is to
the left, subtract it from 65536. Send the resulting number using this
formula: total number of dots = n1 + (n2 x 256). The command is
ignored if it would move the print position outside the current
margins. A unit is 1/120th of an inch in draft, and 1/180th of an inch

wide letter like W. Proportional character widths are given in the
Appendix. This command overrides fixed cpi fonts. When
proportional is cancelled, the previously selected font is used.

Proportional Width Table
This table lists the widths of your printer’s proportional characters. The
values given are in 360ths of an inch. (For example, a value of 36 is
36/360ths of an inch.) You may need to enter these widths into a special
table for your word processing program so it can calculate the number
of proportional characters that will fit on a line.
The characters with no code indicated are international characters or
graphics. See the table in Chapter 3 for the relevant codes for the
international characters. Also, see the descriptions of the ESC R and
ESC t commands in Chapter 9 for information on how to use these
characters.
The following width table shows each character, its ASCII code
(hexadecimal), and its width. If there are two numbers in the width
column, the second one is for the superscript/subscript version of the
character.

Glossary
Note that these definitions apply specifically to printers. If a word is
italicized, see that topic for more information.
application program
A software program that helps you carry out a particular task, such as
word processing or financial planning.
ASCII
Acronym for the American Standard Code for Information
Interchange. A standardized coding system for assigning numerical
codes to letters and symbols.
auto line feed
When this feature is enabled using a DIP switch or external control
through the parallel connector, the printer will automatically feed the
paper one line after receiving a CR code.
baud rate
A measure of the speed of data transmission. Usually expressed in bits
per second or bps.
bidirectional printing
Printing in which the print head alternates printing a line left to right
then the next line right to left, and so on. Because the head prints in
both directions, the overall printing speed increases by eliminating
wasted (non-printing) movement.
binary
See number systems.
bit
A binary digit (0 or 1), which is the smallest unit of information used
by a printer or computer. See also number systems.
buffer
See input buffer and memory.
Glossary 1
byte
A unit of information consisting of eight bits.
carriage return (CR)
The control code that returns the print position to the left margin.
When issued together with a line feed, the print position moves to the
left margin of the next line. In bidirectional printing, the print head
may not physically move to the left margin.
character set
A collection of letters, numbers, and symbols that provides you with
the characters used in a particular language.
condensed
Printing in which each character is approximately 60 percent of the
width of standard characters. For example, condensed 10 characters per
inch (cpi) has 17 characters per inch. Useful for fitting wide tables or
spreadsheets onto the paper.
continuous paper
Paper which has sprocket-feed holes on both long edges, is perforated
between pages, and is supplied in a folded stack. Also called fanfold
paper.
control code
In addition to the codes for printable characters, the ASCII standard
also includes 33 other codes which are called control codes. These
control codes perform such functions as sounding the beeper and
performing a carriage return or line feed.
cut sheet feeder (CSF)
An optional, detachable device which automatically feeds single sheets
of paper into the printer.
data dump
Sometimes called hex dump. A troubleshooting feature. When the
printer is in the data dump mode, each code that it receives is printed in
hexadecimal notation.
2
Glossary
decimal
See number systems.
default
A value or setting that takes effect when the equipment is turned on,
reset, or initialized.
DIP switches
Small switches in a printer that control various printer functions and set
the default status of the printer when it is turned on or initialized. DIP
stands for Dual In-line Package.
dot graphics
A graphic design formed by patterns of dots. Also called bit image
graphics.
dot matrix
A method of printing in which each letter or symbol is formed by a
pattern (matrix) of individual dots.
double-high printing
Printing in which each character is twice as tall as normal.
double-strike printing
A way of producing bolder characters. Each character is printed twice;
the second time, the dots are printed slightly below the original dots.
Can only be used in draft mode.
double-wide printing
A print width in which each character is twice as wide as normal
characters. (The cpi is halved.)
draft mode
One of two print qualities available on your printer. Draft uses fewer
dots per character for high-speed printing. See also Letter Quality.
emphasized printing
A way of producing darker characters. In a single pass of the print
head, characters receive twice the number of dots.
Glossary 3
Epson Extended Graphics character table
The Epson Extended Graphics character table contains international
accented characters, Greek characters, and character graphics for
printing lines, corners, and shaded areas.
ESC (escape) code
A special control code used to begin most printer commands.
ESC/P
Abbreviation for Epson Standard Code for Printers. The system of
commands lets you perform software control of your printer from your
computer. It is standard for all Epson printers and supported by most
application software for personal computers.
font
A font is a style of type designated by a family name.
form
In printer terminology, a form normally refers to a page.
form feed
Refers to both a control code and a panel button that advances the
paper to the top of the next page.
hexadecimal (hex)
See number systems.
initialize
To establish the initial default status of the printer by turning the printer
on or by sending an INIT signal or code.
input buffer
The memory in the printer in which data sent from the computer is
stored while waiting to be printed.
interface
The means of connection between the computer and printer. See also
parallel interface and serial interface.
italic
A typestyle in which the characters slant. This sentence is italicized.
4
Glossary
Letter Quality
One of two print qualities available on your printer. Letter Quality
provides better readability and appearance at a reduced print speed.
See also draft mode.
line feed
Both a control code and a panel button that advances the paper one
line space.
loading position
The position to which the paper is automatically loaded. It can be
adjusted by using the micro-adjustment feature.
memory
The printer, like a computer, has a memory. When you print a file from
a computer, the contents of the file are transferred quickly from the
computer’s memory to the printer’s memory. The printer then prints
information from its own memory at a much slower rate. This way of
printing frees the computer to do other work while the printer is still
working. The printer memory is sometimes called the buffer memory or
input buffer.
micro-adjustment
A feature that adjusts the paper loading and short tear-off positions by
the smallest possible increments.
number systems
Three number systems are commonly used with printers:
decimal is base 10 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
(This is the most familiar system.)
hexadecimal (hex) is base 16 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7,
8, 9, A, B, C, D, E, and F. This is frequently used by programmers.
Any decimal number between 0 and 255 can be expressed by a twodigit hex number.
Glossary 5
binary is base 2 and uses only the digits 0 and 1. All information in
computer systems is handled in binary form represented by electrical
signals that are on or off. A binary digit is often called a bit: any
decimal number between 0 and 255 can be expressed by an eight-bit
binary number.
on line
When the printer is on line, it is able to communicate with the
computer connected to it.
paper-out sensor
A small switch behind the platen that sends a signal when it is not in
contact with paper, informing the printer and remote computer that
there is no paper loaded, and causing the PAPER OUT light to go on.
paper tension unit
The part of the printer that fits above the platen to assure proper paper
tension in the printing area.
parallel interface
An interface that connects the computer and the printer. A parallel
interface transmits data one character or code at a time. See also serial
interface.
platen
The black roller that provides the backing for the paper during
printing.
print quality
Your printer has two types of print quality; draft and Letter Quality.
Draft is for high-speed, draft quality jobs; Letter Quality is used to
produce more polished documents.
proportional printing
Printing in which the character width varies from character to
character. For example, a capital W receives much more space than a
lowercase i. The result looks more like a typeset book than a
typewritten draft.
6
Glossary
pull tractor unit
An optional device that feeds continuous paper and multi-part forms
through the printer.
push tractor
A built-in device that feeds continuous paper through the printer.
RAM
Acronym for Random Access Memory. The portion of the printer’s
memory used as a buffer and as a place for storing user-defined
characters. All data stored in RAM is lost when the printer is turned
Off.
reset
To return a printer to its defaults, either by a command, an INIT signal,
code, or by turning the printer off and on.
self test
A method of checking the operation of the printer. When the self test is
run, the printer prints out its current DIP switch settings and the
characters that are stored in its ROM (Read Only Memory).
serial interface
A serial interface transmits data one bit at a time. See also parallel
interface.
short tear-off
A feature that automatically feeds the perforation of continuous paper
to the tear-off position to be removed by the operator, and then draws
the paper back to the loading position. These positions can be adjusted
using the micro-adjustment feature. See also micro-adjustment and
loading position.
10 cpi
A character spacing of 10 characters per inch. This is often the standard
or default pitch. Also referred to as pica.
tractor
The part of the printer that moves continuous paper through the printer
by its sprockets gripping the holes in continuous paper.
Glossary 7
12 cpi
A character spacing in which each character is slightly narrower than
normal, so that there are 12 characters per inch. Also referred to as
elite.
unidirectional printing
Printing in one direction only. Allows more precise vertical alignment
than bidirectional printing. Often used for printing graphics.
user-defined characters
Characters that are defined and stored in the printer by the user. Also
known as download characters.
